Your existing telephone system - upgraded.

What is SIP Trunking?

SIP Trunking refers to the use of VoIP to connect your premise based phone system to the Internet. A broadband or Internet connection replaces traditional, plain-old-telephone (POTs) or Primary Rate Interface (PRI) lines, allowing your organization to communicate more efficiently with better scalability.

SIP Trunking may be utilized with virtually any PBX system, including modern IP based phone systems or older styled analog systems. The older systems may require an integrated access device (IAD) to bridge the SIP connection to your PBX. Either way, SIP Trunking will bridge your company to the modern communications cloud, helping connect all office and mobile users together.

How SIP Trunking Works

SIP Trunking is an excellent way to take advantage of VoIP, while keeping your investment to a minimum, by utilizing your existing telephone system hardware. SIP Trunks will provide you with additional functionality and prepare to move to a fully Hosted PBX solution in the future.

As a successful business, you’re constantly searching for the next big thing. Whether you’re a small business looking for the flexibility and cost savings of VoIP, or a mid-sized company looking for business continuity and flexible calling plan options, we’ll help you save time and money over your traditional telephone services.
